HOSE-COUPLING.

Specification of Letters Patent. Patented J 11116 13, 1916- Applicationfiled July 15, 1915. Serial No. 40,107.

To all whom it may concern Be it known that we, MARSHALL HUBBARD andSAMUEL EDWARD HUBBARD, citizens of the United States of America,residing at 1610 Carey street, Ashland, VJisconsin, have invented.certain new and useful Improvements in Hose-Couplings, of which thefollowing is a specification.

The present invention relates to new and useful improvements in hosecouplers and has for its object to provide means whereby a hose may beeasily and readily connected or coupled to a street water plug or thesections of a hose may be coupled together in an expeditious manner.

A further object of the invention is to provide a coupler of thecharacter described that will be strong, durable and eflicient, simpleand comparatively inexpensive in the manufacture of the same and-alsoone in which the several parts will not be liable to get out of workingorder.

With the above and other objects in view the invention consists of thenovel features of construction, combination formation of parts as willbe hereinafter more fully described and particularly pointed out in theappended claims.

In the accompanying drawings has been shown the simple and preferredforms of the invention it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but the right is hereby reserved to make any changes, alterations ormodifications to which recourse may be had without departing from thespirit of the invention and sacrificing the etliciency of the same.

In the drawings: Figure-1, is a fragmental view of an ordinary streetwater plug showing one cap thereof in elevation and the other cap andone outlet opening of the plug partly in section. Fig. 2, is a verticalsection through the hose coupling. Fig. 8, is a front elevation of theoutlet opening of the plug or the male member of the coupling. Fig. 4,is a front elevation of the female member or the section of the couplingwhich is secured to the hose. Fig. 5, is a front elevation of the capwhen removed from the plug and illustrating a slightly modified form ofthe invention and, Fig. 6, is a vertical section through the same.

Referring now more particularly to the drawing like and correspondingparts are designated by similar reference characters throughout. I

The numeral 1 indicates an ordinary type of a street water plug havingthe usual discharge pipe or opening 2.

In Fig. lthe covers or caps are shown applied to'the discharge openingsand when these caps are removed the hose is to be coupled thereto. Thecaps 3 are formed of one integral member forming a rear nipple portion4: and a flanged portion 5. In the first figure of the drawing thedischarge opening is provided with a flange or ring 6 and the outer faceof this ring is provided with threaded recesses spaced equidistant apartfor the reception of the bolts 7 These bolts project from the ring. andare each provided with an enlarged head 8. Formed within the flangedportion 5 of the cap and spaced equidistant apart are openings 9 whichare a little larger in diameter than the exterior diameter of the boltheads 8 whereby the bolt headsmay be easily and readily inserted withinthe openings. Each opening 9 is connected with an elongated slot 10which is arranged concentrically within the flange 5. From the foregoingit is obvious that by inserting the bolt heads through the openings 9and turning the cap the shank portions of the bolts will travel withinthe slots 10 and the heads of thebolts will rest on the outer face ofthe cap thereby locking the cap upon the discharge opening .of the plugand preventing any longitudinal movement of the cap which would cause aseverance of the cap due to the water pressure contained within theplug. The cover can be readily removed by turning the same to the rightuntil the bolt heads again register with the openings 9 and then bypulling outwardly onthe cap until the same is free of the bolts. Oftenwhen the caps have been applied to the plugs for some time rust orcorrosion takes place thereby making it difficnlt to remove the same. InFig. 1 the cap is provided with three recesses 11 in the'face thereoffor receiving an ordinary spanner wrench whereby a firm grip may beobtained upon the cap for removing the same. In Figs. 5 and 6 the outerperiphery of the cap is provided with two diametrically oppositearranged lugs 12 to which another form of spanner Wrench may be attachedfor turning the cap in removing the same.

Whenthe covers or caps are connected to the plug the improvedconnection'des'cribed 'will hold each cap at three points, that is wherethe bolts extend through the cap and to make a stronger connection byproviding additional slots within the fiange 5 would be impossible as itwould weaken the same. To insure a stronger connection the nipple 4 isprovided with peripheral lugs 18 which are three in number. These lugsare adapted to be inserted within the longitudinally extending slots 1formed within the flange 6 of the discharge pipe. As the cap is beingturned when applied to the plug the lugs 13 will travel within theconcentric grooves 15 thereby providing additional means for connectingthe caps to the plug.

In Fig. 2 the hose is shown as coupled in position to the ring 16 whichmay be a portion of the plug or attached to another section of the hose.Instead of forming the flange or ring 6 integral with the discharge pipeof the plug as shown in Fig. 1 the ring 16 in Fig. 2 is provided with aninternal threaded flange 17 which may be connected to the threaded endof an ordinary discharge pipe of a water plug instead of providing aspecially designed discharge pipe as that shown in Fig. 1.

The numeral 18 indicates the threaded discharge pipe, but this may be asection of the hose when it is desired to use the coupling forconnecting the sections of a hose together.

The ring 16 is also provided with bolts 7, and grooves 15 the same asthe flange 6. The female member of the coupling comprises'a ring 19having an opening therein of less diameter than the opening formedwithin the ring 16. A threaded flange 20 extends rearwardly from thering 19 to which may be connected the hose indicated by the numeral 21.Openings 22 are also provided within the ring 19 having communicatingtherewith the elongated slots 23. The openings :22 are for receiving thebolt heads Sand by forcing the female member inwardly and then turningthe same to the left the shank portions of the bolts will travel withinthe slots 23 and thereby lock the members of the coupling together. Byturning the female member to the right until the openings 22 againregister with the bolt heads the female member may be removed by pullingoutwardly on the same. The outer face of the ring 19 is provided with arecess 2% for the reception of apacking ring 25 and a flanged retainer26 is provided for holding the packing in place.

Having fully described the invention and what we claim as new and desireto secure by Letters Patent is 1. A coupling comprising a ring havingthreaded recesses formed in the. outer face thereof, bolts detachablymounted within the threaded recesses and extending outwardly from theouter face of the ring, a second ring adapted to be secured to the firstmentioned ring and having elongated slots formed therein for thereception of the shanks of said bolts and one end of each I slot havingan enlarged portion for the re ception of the heads of said bolts, thesecond mentioned ring having an opening therein of less diameter thanthe opening of the first mentioned ring, the outer face of the secondmentioned ring having a recess there in, a packing ring arranged withinsaid re cess adapted to lie flush with the outer face of the secondmentioned ring and having an opening therein of the same diameter as theopening of the second mentioned ring and the outer face of said ringsadapted to be held in close Contact when coupled together, substantiallyas and for the purpose set forth.

2. In a device of the character described, a coupling comprising twomembers, one of the coupling members comprising a circular ring, aninternally threaded flange extending outwardly from one face of saidring and adapted to be detachably connected to the discharge pipe, saidring having an opening therein of the same diameter as the openingwithin the discharge pipe, the opposite face of the ring having threadedrecesses therein, bolts mounted within the said recesses and extendingoutwardly therefrom, the other coupling member comprising a ring havinga threaded flange extending from one face thereof, the opposite face ofsaid ring having a recess formed therein. a packing 'ring secured withinsaid recess, the second coupling member having an opening therein ofless diameter than the opening of the first mentioned coupling member,the outer faces of said coupling members adapted to lie in close contactwhen locked to gether, the ring of the second coupling member havingelongated slots therein for the re ception of the shank portions of saidbolts and the ring of the second mentioned coupling being held in closecontact to the ring of the first mentioned coupling between the outerface of the ring of the first mentioned coupling member and the heads ofsaid bolts.

In witness whereof, we hereunto subscribe. our names to thisspecification in the pres ence of two witnesses.
